Choosing my Yandere Best Friend

A happy family, a loving girlfriend, good friends, and reliable coworkers. I had all of those. Until I fell into a coma. They registered me as brain dead. I wasn't. I heard everything. I heard my girlfriend and parents unable to wait for me to die. Waiting for them to cash out the insurance. I heard people coming in, none of them wanting to be at my side. Only out of obligation or to get pity. Only one person came before they pulled the pug on my life. The friend that supported me all my life. Creeped me out at times but always just so reliable. "I know they killed you. I'm going to kill them all. Everyone that's hurt you. I don't know who killed you so I'll kill them all. I should have locked you up when I had the chance. Why didn't I? I'll follow you after you die. Once everyone else is dead I'll follow you and I'll be a girl next time. I lock you up. You'll never leave me." Although those words creeped me out I realized that meant he was the only one who cared. I vowed in the next life, who cares if he's a little creepy. He actually cares about me. Then I died, and woke up. 7 years in the past. This time I'll avoid the pain. Hey yandere best friend. I don't need anyone else. *Trigger Warning* Violence, Straight up Torture, Stalking
